Pythagorean theorem calculator.

You should get 20.78 (rounded) just like everyone else has, however, if you want the very exact form of this perhaps for validity or bonus points...

20.78... = 12 \sqrt{3}

Use the pythagorean theorem
a squared plus b squared equals c squared where c is the length of the hypotenuse and a and b are the lengths of the legs in a right triangle
c^2-b^2=31^2-23^2=432
432=a^2
a=approx 20.7846

34. Samir can rent a moving truck from
nadezda [96]

The true statement is that renting from Company B will be cheaper if Samir drives the truck 100 miles. Then the correct option is D.

<h3>What is a linear equation?</h3>

The linear equation is given as,

y = mx + c

Where m = the slope of the line

c is the y-intercept of the line.

Let y be the total amount and x be the number of miles.

Samir can rent a moving truck from Company A for $35 plus $0.50 per mile. Then the equation will be

y = 0.5x + 35   ....1

Company B for $25 plus $0.70 per mile. then the equation will be

y = 0.7x + 25     ....2

For the same rent, the number of miles will be

0.7x + 25 = 0.5x + 35

0.2x = 10

x = 50 miles

Renting from Company B will be cheaper if Samir drives the truck 100 miles. Then the correct option is D.

A rhinoceros weight when rounded to the nearest thousand was 4,000 pounds. Which of these is the least the rhinoceros could have
Rudik [331]

Answer:

B- 3,500.

Step-by-step explanation:

This is because 3,500 is the lowest number that can be rounded to 4,000.

3,999 and 4,001 can also be rounded but.. (let me show you an image to help).

3,500 < 3,999 < 4,001.

That goes from smallest to largest numbers that round to 4,000.

Hope that helps. x

According to the Census Bureau, 3.39 people reside in the typical American household. A sample of 26 households in Arizona retir
Vikki [24]

Answer:

t=\frac{2.73-3.39}{\frac{1.22}{\sqrt{26}}}=-2.758    

df=n-1=26-1=25  

p_v =P(t_{(25)}  

Since the p value is lower than the significance level 0.1 we have enough evidence to reject the null hypothesis, and we can conclude that the true mean is significanlty lower than 3.39 personas at 10% of significance.

Step-by-step explanation:

Data given and notation  

\bar X=2.73 represent the sample mean

s=1.22 represent the sample standard deviation

n=26 sample size  

\mu_o =3.39 represent the value that we want to test

\alpha=0.1 represent the significance level for the hypothesis test.  

t would represent the statistic (variable of interest)  

p_v represent the p value for the test (variable of interest)  

State the null and alternative hypotheses.  

We need to conduct a hypothesis in order to check if the true mean is less than 3.39 persons, the system of hypothesis would be:  

Null hypothesis:\mu \geq 3.39  

Alternative hypothesis:\mu < 3.39  

The statistic is given by:

t=\frac{\bar X-\mu_o}{\frac{s}{\sqrt{n}}}  (1)  

Calculate the statistic

We can replace in formula (1) the info given like this:  

t=\frac{2.73-3.39}{\frac{1.22}{\sqrt{26}}}=-2.758    

P-value

The degreed of freedom are given by:

df=n-1=26-1=25  

Since is a one sided lower test the p value would be:  

p_v =P(t_{(25)}  

Conclusion  

Since the p value is lower than the significance level 0.1 we have enough evidence to reject the null hypothesis, and we can conclude that the true mean is significanlty lower than 3.39 personas at 10% of significance.
